PRECAUTIONS  

This thermostat is intended for use with a low voltage system;  

do not use this thermostat with a line voltage system. If in doubt  

about whether your wiring is millivolt, line, or low voltage, have  

it inspected by a qualified heating and air conditioning contrac-  

tor or electrician.  

CAUTION  

!

Topreventelectricalshockand/orequipmentdamage,  

disconnect electric power to system at main fuse or  

circuit breaker box until installation is complete.  

Do not exceed the specification ratings.  

WARNING  

!

All wiring must conform to local and national electrical codes  

and ordinances.  

Do not use on circuits exceeding specified voltage.  

Higher voltage will damage control and could cause  

shock or fire hazard.  

This control is a precision instrument, and should be handled  

carefully.Roughhandlingordistortingcomponentscouldcause  

the control to malfunction.  

Do not short out terminals on gas valve or primary  

control to test. Short or incorrect wiring will damage  

thermostat and could cause personal injury and/or  

property damage.

WHITE RODGERS 1F80-51 Programmable Electronic Digital Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: Programmable electronic digital thermostat Installation and operation instructions Operator: Save these instructions for future use. Failure to read and follow all instructions carefully before installing or operating this control could cause personal injury and/or property damage. Description: LCD continuously displays set point, and alternately displays time and room temperature. Temperature range 45° to 90°F. Battery powered (3 “AA” Energizer alkaline batteries included). This thermostat is intended for use with a low voltage system; do not use this thermostat with a line voltage system. All wiring must conform to local and national electrical codes and ordinances. Setpoint temperature range: 45°F to 90°F (7°C to 32°C). Operating ambient temperature range: 32°F to 105°F.
• Page 2: INSTALLATION Remove old thermostat Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. Disconnect the wires from the old thermostat one at a time. Do not let wires fall back into the wall. Install new thermostat using the following procedures. Electric/Gas switch Read entire paragraph before setting electric heat switch. If you are unsure of your application, contact a qualified serviceperson. If you have a single-stage heat pump system, the switch on the back of the thermostat base must be moved to the “ELECTRIC” position. Attach thermostat base to wall Remove the packing material from the thermostat. Gently pull the cover straight off the base. Connect wires beneath terminal screws on base using appropriate wiring schematic. This thermostat is set to operate properly if you have a forced-air heating system. If you have a hydronic heating system, you must set the thermostat to operate properly with your system. This thermostat requires 3 “AA” alkaline batteries to operate. Batteries are installed in the thermostat at the factory with a battery tag to prevent power drainage.
• Page 3: Jumper wire must be connected between thermostat's RH and RC terminals for proper thermostat operation with this system. Typical wiring diagram for heating only, 2-wire, single transformer systems or millivolt systems. Jumper wire must be added between R and B terminals on the primary control. Typical wiring diagram for heat/cool, 4-wire, single transformer systems. Reversing valve is energized when the system switch is in the COOL position. Typical wiring diagram for heat pump with cool active reversing valve. Move fan switch to AUTO position. The blower should stop immediately. If at any time during testing your system does not operate properly, contact a qualified serviceperson. Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it. Press to adjust thermostat setting above room temperature. The heating system should begin to operate.
• Page 4: Move the system switch to the cool position. This thermostat has a built-in short-term (5-minute) time delay. During this 5-minute period, cool will flash on the display indicating that the thermostat has locked out the compressor. To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, do not operate the cooling system. Before you begin programming your thermostat, you should be familiar with its features and the display. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, gently pull it straight out from the base. The following buttons and switches are located behind the door on the bottom of the thermostat cover. The display alternately shows the current time and temperature. Cool is displayed (non-flashing) when the system switch is in the cool position.
• Page 5: Temperature display adjustment allows you to match your old thermostat within a ±4° range. You can enter both heating and cooling programs simultaneously, eliminating the need for seasonal reprogramming. Temperature override lets you temporarily set a desired temperature until the next program period begins. The thermostat can hold any temperature indefinitely without reverting to the programmed setting. It's recommended to program temperatures cooler when the building is vacant or during low activity periods. The thermostat can display temperatures in either Celsius or Fahrenheit. You can switch between 12-hour and 24-hour clock displays based on your preference. The factory preprogrammed settings include specific temperatures and times for heating and cooling. A low battery indicator will display when batteries need replacement, limiting programming capabilities. You must program four periods for both weekday and weekend programs, with options for start times and temperatures.
• Page 6: Independently for both weekday and weekend programs, you may select different heating and cooling start times and temperatures. Use the table at the bottom of the page to plan your program time periods and the temperatures you want during each period. Follow these steps to enter the heating and cooling programs you have selected. The thermostat should be programmed in the 12-hour format, then switched to the 24-hour format, if desired. Repeat steps to complete weekend heating programming. If the outside temperature is below 50°F, disconnect power to the cooling system before programming. Follow these steps to check your thermostat programming one final time before beginning thermostat operation. Press RUN PRGM once to begin program operation. Your thermostat is now completely programmed and ready to automatically provide maximum comfort and efficiency.
